When the diaphragm and external intercostal muscles contract, which of the following actions does NOT occur?
A. Air moves into lungs
B. The diaphragm moves inferiorly
C. The intrapulmonary pressure decreases
D. The intrapleural pressure increases.
If the transpulmonary pressure equals zero,a. a pneumothorax has probably occurred.b. the lungs cannot inflate.c. elastic recoil causes the lungs to collapse.d. all of these apply.
How would paralysis of the diaphragm alter inspiration? a. It would prevent contraction of the intercostal muscles. b. It would prevent inhalation because the intrapleural pressure would not change. c. It would decrease the intrapleural pressure and allow more air to enter the lungs. d. It would slow expiration because the lung would not relax.
